Title: Improvements in temperature regulating systems
IPC: G05D23/275
Filed: 1933-11-25
Abstract: 417,630. Electrically-actuated valves. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Vapor Car Heating Co., Inc. ; 80, East Jackson Boulevard, Chicago, U.S.A.) Nov. 25, 1933, No. 33060. [Class 135.] A temperature regulating system wherein in each of several compartments X, Y, Z thermostatic devices A, A<1>, A<11> comprising several thermometers 103, 104, 105 are provided, each thermometer being adapted to make a contact at a particular temperature and there also being provided in each compartment a selector 110 to connect one of the thermometers in a circuit to a relay which in turn energizes an actuating means for a valve controlling the flow of heating fluid to the compartment. Mounted upon a panel C are relays D, D<1>, D" which are connected to the thermostatic devices A, A<1>, A<11> respectively and operate solenoid motors B, B<1>, B<11>. Upon contact taking place of one of the thermometers selected by the arm 110 in a compartment, the solenoid 87 of a relay is short circuited and the core 88 falls allowing the contacts 93, 94 to be bridged by the plate 90 and thus energizing solenoid 130 to close the valve 124. A switch 136 is moved after the valve is closed to break the circuit to the solenoid 130 and make a circuit to the solenoid 131 in readiness for the next operation which occurs when the temperature falls and the solenoid 87 is energized and the contacts 91, 92 are bridged and the solenoid 131 is energized to open the valve. The source of power is derived from a battery H and a generator J, which in the case of a railway vehicle is driven from the axle 2, arranged in parallel and a switch 10 being adapted to close only after a solenoid 13 is sufficiently energized. The circuits between the thermostats A, A<1>, A<11> and the relays D, D<1>, D<11> are fed by current controlled by the voltage regulator K comprising a rheostat 29, the pressure on which is adjusted by the solenoid 39. The regulator K also controls the current to the lamps L for lighting the compartment. The circuits between the relays D, D<1>, D<11> and the actuating mechanism B, B<1>, B" are supplied direct by the battery, generator combination. Should the current taken by the devices B, B<1>, B<11> be excessive or the time of action prolonged, then a strip 75 is warped and the circuit broken and an indicating lamp 85 is illumined. Switches 148 are fitted to each relay so that each circuit may be broken. A switch arm 159 is actuated by a Bourdon tube 153 connected to a pressure line in which the pressure is released when the railway vehicle is uncoupled. When the pressure is released the contacts 156, 157, 158 are bridged and solenoid E energized to make the contacts 173, 174 so that whatever the position of the switches 148 or the selectors 110, the valves of all compartments are controlled to maintain a minimum temperature.

Abstract: 839,219. Impedance matching. STANDARD TELEPHONES & CABLES Ltd. Oct. 25, 1957 [Oct. 30, 1956], No. 33390/57. Class 40 (8). [Also in Group XL (c)] A microwave mixer circuit comprises mixer crystals arranged in a hollow guide which on one side of the crystals includes an axial conductor so that on one side H10 mode waves are supported and on the other TEM waves, the arrangement further being such that the H10 waves will not pass to the TEM wave source and vice versa. In the Figure two mixer crystals 7, 8 are connected to a central conductor 2 in a wave-guide 1. A first signal is applied to the waveguide to produce H10 waves and a second signal is applied to a second waveguide 3 and injected into the waveguide 1 in the form of a TEM wave by means of an adjustable probe 4. This wave cannot pass along guide 1 beyond the end of the conductor 2 and the H10 wave cannot pass through the coupling between the guides to guide 3. The two mixer crystals may be arranged in between laterally extending housings as shown in Fig. 4 between conducting strips 15, 26 extending to the side walls of the guide. The I.F. signal may be extracted from a coil 25, D.C. being applied to the crystal through a potentiometer 23 which may be adjusted so that the crystals are balanced. The circuit may be further balanced by means of a screw 27 which adjusts laterally the position of conductor 26. In alternative arrangements (Figs. 2 and 3, not shown), the two crystals are arranged in push-pull and parallel respectively.

Title: Improvements in or relating to automatic control systems for impedance matching networks
Inventor: BROWN THOMAS THEODORE
IPC: H03H7/40
Filed: 1954-11-18
Abstract: 785,838. Automatic control systems for impedance matching networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 5, 1955 [Nov. 18, 1954], No. 33396/54. Class 38 (4). A network for coupling a radio transmitter to the aerial having a series-connected tuning inductance automatically adjusted by a reversible electric motor to maintain the circuit at resonance, in response to a phase discriminator, and a shunt connected impedance matching inductance automatically adjusted by a second reversible electric motor to maintain the impedance matched to the aerial, has an auxiliary circuit responsive to low input impedances which over-rides the tuning control to prevent incorrect functioning. It is shown that as the tuning inductance is reduced from a maximum through and beyond resonance, the phase angle of the input current reverses not only at resonance but also a second time, thereby causing the phase discriminator to control the tuning motor in the wrong direction once this point of inversion is reached. It is also shown that beyond the point of inversion the ratio of input impedance to aerial impedance is less than 2. It is arranged that this ratio shall be normally greater than 2 (5 is suggested), hence any reduction of input impedance below a predetermined value indicates incorrect operation. The aerial RA is coupled to the transmitter (not shown) by the tuning inductance LS and impedance matching inductance LP. A first impedance comparator B controls a reversible electric motor MB through amplifier 10, 11, 12 and relays 13, 14 to adjust inductance LP. A phase discriminator A controls a reversible electric motor MA through amplifier 1 . . . 4 and relays 5, 6 to adjust inductance LS. A second impedance comparator C controls a relay E through an amplifier 7, 8 to run the motor MA in a direction to increase the inductance LS if the input impedance falls below the predetermined level.
